When a pit fighter needs cash for urgent, life-saving medicine, she reluctantly agrees to spy for the resistance—even as the governor’s son watches her every move—in this fast-paced young adult dystopian romance that’s Silver Elite meets Coldwire.

Proxima “Xi” Gaines was able to survive a deadly outbreak when antibiotics failed thanks to her genetically engineered immune system. Now she scrapes together a living for herself and her twin brother, Ry, as an underground fighter beneath Old Boston’s contaminated, crime-ridden streets. The healthy residents of New Boston pay big bucks to watch rival gangs fight, and notorious mobster Mama sees potential—and profit—in Xi.

Until Xi’s immune system turns against her.

Suddenly her fighting days are numbered. She’ll do anything to afford the pricey pills needed to save her life, so when the Revolutionaries approach her with an opportunity that might just change everything, she seizes it. Xi will have to fight in New Boston’s Centennial Celebrations as a front to spy on the Governor General—a task made all the more difficult with the governor’s roguish son, Logan, watching her every move, convinced Xi is up to no good.

If she succeeds, the Revolutionaries will give Xi and her brother a new life, one that includes access to medical care she desperately needs. Fail, and she’s as good as dead.

If she wants to survive, Xi will have to hide her symptoms—and her growing feelings for Logan—long enough to uncover the plot that could forever alter both Bostons…and her future.
